Katanasound is a Japanese boutique effects pedal maker established in March 2003, building hand-wired guitar and bass pedals in small numbers. The brand grew out of the founder's experience repairing and studying expensive vintage Western pedals imported into Japan in the 1990s, an exercise that informed a design approach centered on simple, carefully laid-out circuits and hand-selected components.

The catalog leans heavily on gain and fuzz. Signature models include the Furious Man multifaceted fuzz, the Raging Wave classic fuzz, the Thundercloud overdrive-fuzz, the Super Bass Fuzz octave fuzz aimed at bassists, the Venomous Snake octave fuzz inspired by the Tycobrahe Octavia, and the Volcanic Eruption octave fuzz. Alongside these, the range covers overdrive with the Kamikaze and Kamikaze Supreme, the Albatross British overdrive, the Blue Stripe compressor/limiter, the Shimmer tremolo, and the Soul Baby wah.

The brand has a niche following among Japanese pro players and boutique pedal enthusiasts abroad. In the United States, Andy Babiuk's Fab Gear has served as the official distributor.

Katanasound has 3 products cataloged on Equipboard, including Fuzz Effects Pedals and Compressor Effects Pedals. Their gear is featured by 2 artists, with the strongest followings in Rock. Notable users include Takaaki Mino and Margarette Hiroi.
